Embodiment Construction

[0035] Such as Figure 1-7 As shown in one of them, the quick joint for high-pressure pipeline of the present invention includes a first joint 1 and a second joint 2 provided with butt ends, and the other ends of the first joint 1 and the second joint 2 are respectively used to connect the upstream high-pressure pipes and downstream high-pressure pipelines, the butt ends of the first joint 1 and the second joint 2 are correspondingly provided with a first one-way valve 3 and a second one-way valve 4 that are plugged and communicated with each other, and the first one-way valve 3 has The elastic force of the first spring 31 is greater than the elastic force of the second spring 41 that the second one-way valve 4 has. There is a device between the first one-way valve 3 and the second one-way valve 4 for controlling the connection between the second one-way valve 4 and the first one-way valve. The one-way valve 3 is connected to the on-off fastening device 5; when the first one-w...

Abstract

The invention relates to a high-pressure pipeline rapid connector. The rapid connector comprises a first connector body and a second connector body which are provided with butt joint ends. The other ends of the first connector body and the second connector body are separately used for being connected with an upstream high-pressure pipeline and a downstream high-pressure pipeline. The butt joint ends of the first connector body and the second connector body are correspondingly provided with a first one-way valve and a second one-way valve which communicate with each other in an inserted mode. A first spring arranged on the first one-way valve is larger than a second spring arranged on the second one-way valve in elastic force. A fastening device used for controlling connecting on-off of the second one-way valve and the first one-way valve is arranged between the first one-way valve and the second one-way valve. When the first one-way valve and the second one-way valve are connected in an inserted mode, under the elastic force effect of the second spring, the second one-way valve is firstly opened and then pushes the first one-way valve to be opened and to communicate with the second one-way valve. The high-pressure pipeline rapid connector is reasonable in design, compact in structure, good in airtightness, easy and convenient to operate and rapid in connection, the flow area and flow of a flow channel after communication are stable, and a large flow coefficient is achieved.

Description

technical field [0001] The invention relates to the technical field of quick joints, in particular to a quick joint for high-pressure pipelines. Background technique [0002] A quick connector is a connector that can be connected or disconnected by plugging and unplugging without tools. Quick joints for high-pressure pipelines have certain requirements for the material, sealing form and safety structure of the joints due to the high maximum working pressure when connecting high-pressure pipelines. Although there are many types of quick connectors on the market, most of them have the following defects: [0003] 1. The pressure resistance of the joint is low; [0004] 2. The manufacturability of the joint is poor, the sealing ability is poor, and the service life is short; [0005] 3. When the joints are docked, the required operating force is large and the operation is inconvenient; [0006] 4. After the joint is connected, the internal flow area is unstable, resulting in...
